This article investigates the physicochemical and structural properties
of TU-90 grade carbon black according to ASTM standards. During the study, the oil
absorption number (OAN), compressed oil absorption number (COAN), and iodine
adsorption number were determined, and the structural stability and dispersity of the
carbon black were evaluated. The obtained results demonstrated that the TU-90
sample possesses a medium-high structural morphology, high mechanical strength,
and enhanced abrasion resistance. Analyses carried out according to ASTM D3493
and ASTM D1510 standards scientifically substantiated the possibility of using TU-
90 carbon black as an effective reinforcing material in rubber and polymer
composites.
